Service and support
High pressure water jets erode core particles then recirculate within machine
Good method for simple core geometry. Low health and safety issues.
Can be difficult and time consuming to remove the core.
Grit or shot is fired at the core passage within a cabinet either by compressed air or an impeller.
Effective at removing large cores with low complexity. Low health and safety issues. Good casting finish
High level of dust. High possibility of casting wear.
Sodium or potassium hydroxide solution (35 – 50%) in a tank at room or elevated temperature. Parts placed into solution and left for liquid to break down the core material. Mechanical or air agitation may be added.
Low cost, simple method for removing cores. Minimises erosion of casting.
Can take long time for large or complex cores. High level of health, safety and environmental risks
